What happened to me is I made an extremely potent marijuana edible. I had basically a full pack of Marlboro reds on my desk. I ate the edible and it scared the crap out of me. I started thinking about my lungs and all the damage I have done over the years. It was surreal and the edible really made me see it clearly. I started to notice my breathing wasn't quite right etc.. after the edible the next day I didn't touch my cigarette. I had that pack of Reds on my desk for 6 months until I gave it to someone who needed some. I quit smoking then and there for two years. Only picked it back up after my Fentanyl addiction when my mom died. I asked for a cigarette and off to the races I went. Now I smoke menthol which I always hated before lol. I might try the edible thing again. I don't smoke marijuana anymore so it would be super intense I know it. I'm scared I might start thinking terrible things and go into a psychosis of sorts. But the edible did work so I can see how things like shrooms could make a person quit nicotine and opioids if done correctly
Maybe, BUT you don't need to do that. Actually you can use a visualization technique to have the person imagine the "thing" and then change it. For example, you have them imagine eating chocolate then you have them add really gross things to it until you reach a level of disgust. Same with a cigarette, just have them imagine nasty things in and around smoking, then you change a few of the characteristics of the way they imagine seeing, hearing, smelling and tasting the cigarette, also things like colors and distance and after a short while "Boom!" they don't want the thing anymore and if NLP visualizations aren't enough you can use EFT (a form of Chinese acupressure/medicine) and or hypnosis.
Why would you tell his story when you can go on RU-vid and let him tell the cigarette store himself find something better to do with your time then waste your time in other peoples time. Doing nothing you think you can tell it anywhere near the level of him, the person that went through it come on man, the blind leading the blind here.
